IMA will use the module_signature format for append signatures, so export
the relevant definitions and factor out the code which verifies that the
appended signature trailer is valid.

Also, create a CONFIG_MODULE_SIG_FORMAT option so that IMA can select it
and be able to use mod_check_sig() without having to depend on either
CONFIG_MODULE_SIG or CONFIG_MODULES.

s390 duplicated the definition of struct module_signature so now they can
use the new <linux/module_signature.h> header instead.

IMA policy rules are walked sequentially.  Depending on the ordering of
the policy rules, the "template" field might be defined in one rule, but
will be replaced by subsequent, applicable rules, even if the rule does
not explicitly define the "template" field.

This patch initializes the "template" once and only replaces the
"template", when explicitly defined.

Pull btrfs fixes from David Sterba:
 "Two regression fixes:

   - hangs caused by a missing barrier in the locking code

   - memory leaks of extent_state due to bad handling of a cached
     pointer"

Pull vfs umount_tree() leak fix from Al Viro:
 "Fix braino introduced in 'switch the remnants of releasing the
